Solar Power - The Beginnings

Solar Power - The Beginnings
We started out using solar power to start fires using glass and mirrors to concentrate the sun's rays to get the fire started.

People started building homes in the sides of south-facing cliffs to take advantage of the sun's daytime heat, which was stored in the cliff's surface for later use. This was the forerunner of what's referred to today as passive solar Oakleys Outlet.

The Future Is Solar
The sky's literally the limit where solar's concerned. Soon you'll see solar aeroplanes landing at an airport near you! Cells and panels will get smaller and more efficient, and pretty much anything that's powered by electricity will probably be converted to solar at some point.

But, what I did experience was the most beautiful Alpenglow sailing down through the Lynn Canal to Skagway. As the sun began to rise, the color on the snow-capped mountains began to turn beautiful colors of pink Réplique Lunettes de soleil Ray Ban. It was spectacular and something that I am so blessed to have been awake to see. The pictures truly do not do it justice, but they do serve as a wonderful reminder of a very spectacular morning.Our excursion today was a mushers camp and sled dog "experience". It was really nothing exciting and had we had the choice to do it over again, we wouldn't. It was not what we expected at all. This was a "mushers" camp several miles out of town in the "bush" that was set up with about 300 sled dogs - strictly there for the cruise ship tourists. A large van/bus holding 24 people picked us up at the cruise dock and drove us out to the site.

This was later used by Bell Labs in the 1950s to create the first solar cell that could generate enough electricity to power small electrical equipment. Small solar arrays were used to power satellites in the late 50s, and solar energy is still a prominent feature in today's space programme.

We saw several different sleds and the dogs were all around us. From that point, they put groups of 12 of us at a time into a smaller van and drove us up a steep hill to where they had teams of dogs hoked up to "sleds" which were a six person metal "sleigh" - three rows of two people - on treds that the dogs pulled up a muddy dirt road and back again for about a mile up and a mile back. That was it. We have really been so lucky with our weather. Today it was about 45-50 degrees during the day with spotted clouds. The mountains are so beautiful with all of their snow and so spectacular against the blue sky.After that we were dropped off in town and we strolled the streets looking in the shops and we stopped for lunch Lunettes Ray Ban de sortie, then walked back to the ship along the small boat harbor (about a mile).

As you can tell, solar power has come a long was since the ancient Greeks first used it to start fires. And the great thing is that it still has a long way to go before its potential is anywhere near fulfilled, so here's to the future of solar and all the exciting developments yet to come.

Solar power yesterday and today are basically the same concept, although the technology has come a long way over the centuries. Yes, centuries. That's because solar power, in one form or another, has been with us since the earth was formed. We'll look at solar power past, present and with perhaps a small glimpse into the future.

Greenhouses And Photovoltaics
In the 18th century, Swiss scientist Horace de Saussure was experimenting with the effects of solar power on glass and created what was then known as the "hot box", which eventually was used to create the greenhouse.

With the advent of thin-film technology, the cost of production per watt is now below $1, and, once the efficiency of this technology catches up with its cost, in reverse proportion, solar will become much more affordable to a lot more people.

Solar thermal technology has also come a long way, and supplies heat and hot water to homes and businesses throughout the world. It's also become very popular with pool owners, keeping their pools warm year-round while reducing electrical costs substantially. We see solar used in many situations these days, from calculators to shavers to aeroplanes. You can throw your garbage into a solar trash compactor or pay for your parking using a solar ticket dispenser. What next?

Solar Power Today
Solar power as we know it today has made huge advances in technology and application. Solar, or photovoltaic, panels are so efficient that they can now run entire households and businesses with little or no downside. They're also much cheaper than they were even just a few years ago, and that trend is set to continue into the foreseeable future.

In the 19th century, Frenchman Edmund Becquerel discovered what became known as the "photovoltaic effect", when he found that the sun's light reacted with certain materials to create a small electrical charge.
